The proposal includes gold mining developments within a defined project area on Lake Lefroy a naturally occurring salt lake approximately 7 kilometres south-east of Kambalda. Thirteen sites have already been identified for development of open-cut gold mining pits, some with underground portals and mining. Additional sites may be identified within the defined project area.

Waste rock dumps, access infrastructure and mining support facilities such as workshops and contractor's compounds will be associated with the mining developments. Administration, central maintenance and processing of ore will occur at the existing St Ives Gold operations to the south of the lake.
